Convenient support is provided for up to four aileron
servos and four flap servos on normal models or, for
V tail and flying wing/delta models, up to two aileron/
elevator servos plus four flap servos.
The majority of motorized and glider models belong
to the tail unit type "normal" and are equipped with
one servo each for elevator, rudder and ailerons in
addition to a motor throttle or electronic speed con-
troller (or for brake flaps in the case of a glider mod-
el). Beyond this, tail unit type "2 HR Sv 3+8" permits
the connection of two elevator servos to receiver
outputs 3 and 8.
"V-tail" is to be selected from the »Model type« menu
if the model has a V-tail instead of a "normal" tail.
This V-tail option provides coupled control functions
for elevator and rudder such that both tail flaps – each
controlled by a separate servo – are able to handle
both elevator and rudder functionality.
For delta and flying wing aircraft models, aileron and
elevator functionality is affected by way of a common
rudder flap on the trailing edge of each side (right and
left) of the wing. The program contains appropriate
mixer functions for both servos.
If ailerons, and conditionally the flaps, are each actu-
ated with two separate servos then settings can be
made for differentiated control of all aileron and flap
pairs in the »Wing mixers« menu, i. e. settings for
downward rudder throw independent of upward throw.
And finally, the positioning of flaps can also be con-
trolled by one or even more of the three proportional
sliders or the seven proportional rotary controls.
Alternatively, there is a phase-dependent trim func-
tion available for flaps, ailerons and elevators in the
»Phase trim« menu.
Up to 8 flight phases can be programmed into each of
the 80 model memory locations.
Except for C1 trim, digital trim will be stored on a
flight-phase basis. C1 trim permits easy location of a
carburettor idle setting.
Two timers are always available for flight operation.
The transmitter operating time expired since the last
battery charge is also displayed.
All transmitter controls and switches can be assigned
in the »Control adjust« menu to inputs 5 … 16 with
almost no restrictions.
The "Dual Rate" and "Exponential" functions for
ailerons, rudder and elevators are separately pro-
grammable and each are convertible between the two
variations on a specific flight-phase basis.
In addition to 8 freely allocatable linear mixers, 4 curve
mixers (»Free mixers« menu) and 4 dual mixers
(»Dual mixer« menu) there are also flight-phase de-
pendent 8-point curves available to control channel 1
(throttle/brake), see »Channel 1 curve« menu.
Depending on the number of wing servos, fixed-
definition mix and coupling functions can be selected
from a list in the »Wing mixers« menu.
• Multi-flap menu: control of flaps as ailerons, the in-
fluence aileron trim on flaps controlled as ailerons,

• Brake settings: butterfly, differential reduction,
elevator curves
